Aim: What are the special properties of the special right triangles?
To begin, we will need to review the special right triangles: 45-45-90 and 30-60-90. You will watch two videos to refresh your memory on the special relationships.
Be sure to take notes so you will have something to refer to.
Find the value of the six trig functions for a 30 degree angle, a 60 degree angle, and a 45 degree angle. Be sure all of your anwers are in simplest radical form.
Journal entry: Speculate why the special right triangles discussed in today's lesson are important in the real world.
